IPSec - Site to Site - IPv4 over IPv6 Tunnel
-
I know there is an option in advanced settings for sending IPv6 over IPv4 but is there any way to do the opposite?
I'm trying to form a Site to Site tunnel over IPv6 since the remote endpoint is on a cellular network and it would be slightly easier with IPv6 as the source/destination but I only care about passing IPv4 traffic/routes over that tunnel..
I tried setting things up and the tunnel forms but I can't seem to pass any IPv4 traffic across the tunnel but the Child SA comes up fine. -
So I can ping from the remote side to the local side but return packets don't get back and for some reason are routed normally (ie out to the internet/default route).
Not sure why pfSense is routing packets incorrectly though unless I'm missing some setting.
